Periprosthetic shoulder infection: an overview

Nicolas Bonnevialle et al. EFORT Open Rev. .

Abstract

Periprosthetic shoulder infection (PSI) is rare but potentially devastating. The rate of PSI is increased in cases of revision procedures, reverse shoulder implants and co-morbidities. One specific type of PSI is the occurrence of low-grade infections caused by non-suppurative bacteria such as Propionibacterium acnes or Staphylococcus epidemermidis.Success of treatment depends on micro-organism identification, appropriate surgical procedures and antibiotic administration efficiency. Post-operative early PSI can be treated with simple debridement, while chronic PSI requires a one- or two-stage revision procedure. Indication for one-time exchange is based on pre-operative identification of a causative agent. Resection arthroplasty remains an option for low-demand patients or recalcitrant infection.

a) Radiograph of a 73-year-old man with a chronic periprosthetic shoulder infection of a reverse shoulder arthroplasty (RSA). b) A two-stage revision was decided with a cement spacer implantation for eight weeks. c) Propionibacterium acnes was identified on peri-operative samples taken from the back of the glenosphere. d) After four weeks free of antibiotics, a new RSA was implanted with a proximal humeral allograft.

Radiographs (a and b) of an 86-year-old woman, with a loose implant secondary to chronic periprosthetic shoulder infection. c) Because of numbers of co-morbidities and huge bone loss on glenoid side, a simple resection arthroplasty was performed.
